At 3 miles, you are going to have some difficulty connecting.  Depending on
where you are located, 2.4GHz and 5.7GHz frequencies could be very noisy.
You could build a cantenna, but you would need line of sight and it could be
difficult aligning both sides of the connection.  The first thing I would do
is get up on your roof and your friends roof and see if you can establish a
clear line of sight.  Trees and building are killers for wireless signals.

There are other P-to-P wireless technologies out there from Motorola, Cisco,
Adtran, Orthogon, Redline, and others that also use unlicensed bands that
work very well.  The only problem is cost ($2,000 and up).

Subject: high speed wireless over 3 miles..

ok, I have a few questions.

I would like to create a high speed link device for a friend of mine. he
lives 
far enough away that putting in cable or DSL is not practical and the only 
alternative is to somehow get an 802.11x signal to reach from his place to 
the node where I have setup internet.

any suggestions?

I am looking for DIY/cheap solutions here.
